the standard inheritance sample

Some program sources from "How to C++ program". And I edited some sources. I wanna demonstrate how to make a type casting between base class and derived class.(Certainly, we must type_cast derived class to base class.). I will recount more details later.

strcpy( firstName, first );

strcpy( lastName, last );
}

const char *Employee::getFirstName() const

void Employee::print() const

{

wage = initWage;
}

double HourlyWorker::getPay() const
{ return hours * wage; }

Employee::print();

cout << " is an hourly worker with pay of $"
<< setiosflags( ios::fixed | ios::showpoint )

}

int main()

h.print();

/* Demonstrating how to make base class type casting to derived class */

HourlyWorker *hwPtr = 0, hw( "Job", "Steve", 31.00, 22.00 );

cout << "\n\nePtr->print(), ePtr = &e:\n";
ePtr->print();

hwPtr = static_cast<> ( ePtr );
cout << "\n\nhwPtr->print(), before point to hw:\n";
hwPtr->print();

hwPtr = &hw;
cout << "\n\nhwPtr->print(), after point to hw:\n";
hwPtr->print();
cout << "\n\n";
return 0;

output
--------------------------------------------
mathsniper:~# ./employee1
HourlyWorker::print() is executing
Final Fantasy is an hourly worker with pay of $516.00


ePtr->print(), ePtr = &e:
Stephen Ken

hwPtr->print(), before point to hw:
HourlyWorker::print() is executing
Stephen Ken is an hourly worker with pay of $0.00


hwPtr->print(), after point to hw:
HourlyWorker::print() is executing
Steve Job is an hourly worker with pay of $682.00
